Printed a simple soap tray- it was just a plate printed vertically- 3mm thick with rounded edges.
Prusaslicer settings were 1.5mm fuzzy skin with 2mm connection points, spiral mode with zero bottom infil, and a 3mm brim for adhesion. (The brim is easy to remove, and the edge looks nicer with with no infill.)
100%extrusion width.
It is a rectangle, but the trick is to start the print with the nozzle 1mm off the bed to replicate the texture.
